Among hard materials, icosahedra-based boron-rich ceramics are only second to diamond-
based structures. This class of ceramics possesses lower density, higher thermal and …

In the design of strong solids, especially hard and superhard materials, this review article
attempts to critically cover an extended field of first-principles derived mechanical properties …

Boron carbide has a wide range of solubility, but the effects of stoichiometry on its
microstructure and mechanical response are not well understood. In this study, detailed …

Solid-state shock-wave propagation is strongly nonequilibrium in nature and hence rate
dependent. Using high-power pulsed-laser-driven shock compression, unprecedented high …

Boron carbide is extremely hard but has been shown to undergo stress-induced
amorphization when subjected to large nonhydrostatic stresses. This localized …

Boron carbide (B 4 C) is an important structural ceramic material, however, the use of this
material is limited by its poor sinterability and low fracture toughness. Nano-sized powders …

The observation of fracture behaviors in perfect and twinned B4C crystals via in situ
transmission electron microscopy (TEM) mechanical testing is reported. The crystal structure …

Despite its superior mechanical properties, boron carbide suffers from amorphization, a
pressure-induced phenomenon that disturbs crystalline order and likely reduces shear …

The theoretical strength of a material is the minimum stress to deform or fracture the perfect
single crystal material that has no defects. This theoretical strength is considered as an …

Boron-rich carbides with icosahedral cages as pivotal structural units, which exhibit high
hardness and low density, have promising industrial applications. However, the insufficient …
